Grade 4 Maths Resources (1.5.1 Subtraction of 5 Digit Numbers with ... - Free Printable

Let’s solve each subtraction problem step by step. I’ll go one at a time, carefully subtracting the bottom number from the top number.

Problem 1: 50833 - 35751

Start from the right:

- 3 - 1 = 2
- 3 - 5 → can’t do, borrow: 13 - 5 = 8 (the 8 becomes 7)
- 7 - 7 = 0
- 0 - 5 → can’t do, borrow: 10 - 5 = 5 (the 5 becomes 4)
- 4 - 3 = 1

→ 15082

Wait — let me double-check with direct calculation:

50833
-35751
= ?

50833 - 35000 = 15833
15833 - 751 = 15082 ✔

Problem 2: 84530 - 73430

Easy! Both end in 30.

84530 - 73430 = (84530 - 73000) - 430 = 11530 - 430 = 11100

Or directly:

84530
-73430
= 11100 ✔

Problem 3: 90078 - 34856

Do it column by column:

8 - 6 = 2
7 - 5 = 2
0 - 8 → borrow: 10 - 8 = 2 (but next digit is 0, so need to borrow further)

Actually, better to write:

90078
- 34856
--------

Right to left:

8 - 6 = 2
7 - 5 = 2
0 - 8 → can’t, borrow from left. But left is 0, so go to 9.

Borrow: 9 becomes 8, first 0 becomes 10, then lend to next 0 → that 0 becomes 9, and last 0 becomes 10.

So now:

Thousands place: 9 (after borrowing)
Hundreds: 9 (was 0, borrowed from thousands)
Tens: 10 (was 0, borrowed from hundreds)
Units: already did.

Wait — let's align:

9 0 0 7 8
- 3 4 8 5 6
------------

Start from units:

8 - 6 = 2
7 - 5 = 2
0 - 8 → borrow from left. Left is 0, so go to 9.

Change 9 to 8, middle 0 becomes 10, then lend to right 0 → that becomes 9, and current 0 becomes 10.

Now:

Ten-thousands: 8
Thousands: 9
Hundreds: 10
Tens: 7 → wait no, we’re at hundreds place now.

After borrowing:

Number becomes: 8 9 10 7 8? No.

Original: 90078

We are at hundreds place: digit is 0, need to subtract 8.

So:

Look at ten-thousands: 9 → reduce to 8
Thousands: 0 → becomes 10, but we need to lend to hundreds, so thousands become 9, hundreds become 10.

Now:

Ten-thousands: 8
Thousands: 9
Hundreds: 10
Tens: 7
Units: 8

Now subtract:

Units: 8 - 6 = 2
Tens: 7 - 5 = 2
Hundreds: 10 - 8 = 2
Thousands: 9 - 4 = 5
Ten-thousands: 8 - 3 = 5

→ 55222

Check: 34856 + 55222 = 90078?
34856 + 55000 = 89856; +222 = 90078 ✔

Problem 4: 36366 - 24085

6 - 5 = 1
6 - 8 → borrow: 16 - 8 = 8 (3 becomes 2)
2 - 0 = 2
6 - 4 = 2
3 - 2 = 1

→ 12281

Check: 24085 + 12281 = 36366?
24085 + 12000 = 36085; +281 = 36366 ✔

---

Problem 5: 72643 - 41932

3 - 2 = 1
4 - 3 = 1
6 - 9 → borrow: 16 - 9 = 7 (2 becomes 1)
1 - 1 = 0
7 - 4 = 3

→ 30711

Check: 41932 + 30711 = 72643?
41932 + 30000 = 71932; +711 = 72643 ✔

Problem 6: 66208 - 43276

8 - 6 = 2
0 - 7 → borrow: 10 - 7 = 3 (2 becomes 1)
1 - 2 → borrow: 11 - 2 = 9 (6 becomes 5)
5 - 3 = 2
6 - 4 = 2

→ 22932

Check: 43276 + 22932 = 66208?
43276 + 22000 = 65276; +932 = 66208 ✔

---

Problem 7: 20575 - 12345

5 - 5 = 0
7 - 4 = 3
5 - 3 = 2
0 - 2 → borrow: 10 - 2 = 8 (2 becomes 1)
1 - 1 = 0

→ 8230

Check: 12345 + 8230 = 20575?
12345 + 8000 = 20345; +230 = 20575 ✔

---

Problem 8: 74250 - 53442

0 - 2 → borrow: 10 - 2 = 8 (5 becomes 4)
4 - 4 = 0
2 - 4 → borrow: 12 - 4 = 8 (4 becomes 3)
3 - 3 = 0
7 - 5 = 2

→ 20808

Check: 53442 + 20808 = 74250?
53442 + 20000 = 73442; +808 = 74250 ✔

3 - 2 = 1
6 - 2 = 4
4 - 1 = 3
7 - 5 = 2
3 - 2 = 1

→ 12341

Check: 25122 + 12341 = 37463?
25122 + 12000 = 37122; +341 = 37463 ✔

Problem 10: 45537 - 42840

7 - 0 = 7
3 - 4 → borrow: 13 - 4 = 9 (5 becomes 4)
4 - 8 → borrow: 14 - 8 = 6 (5 becomes 4)
4 - 2 = 2
4 - 4 = 0

→ 2697

Check: 42840 + 2697 = 45537?
42840 + 2000 = 44840; +697 = 45537 ✔

Problem 11: 62865 - 50623

5 - 3 = 2
6 - 2 = 4
8 - 6 = 2
2 - 0 = 2
6 - 5 = 1

→ 12242

Check: 50623 + 12242 = 62865?
50623 + 12000 = 62623; +242 = 62865 ✔

Problem 12: 75628 - 39606

8 - 6 = 2
2 - 0 = 2
6 - 6 = 0
5 - 9 → borrow: 15 - 9 = 6 (7 becomes 6)
6 - 3 = 3

→ 36022

Check: 39606 + 36022 = 75628?
39606 + 36000 = 75606; +22 = 75628 ✔

---

Problem 13: 98500 - 46746

0 - 6 → borrow: 10 - 6 = 4 (0 becomes 9, but previous is 0 too...)

Better:

98500
- 46746
--------

Units: 0 - 6 → borrow from tens. Tens is 0, so borrow from hundreds.

Hundreds is 5 → becomes 4, tens become 10, then lend to units → tens become 9, units become 10.

Now:

Units: 10 - 6 = 4
Tens: 9 - 4 = 5
Hundreds: 4 - 7 → borrow from thousands. Thousands is 8 → becomes 7, hundreds become 14.

14 - 7 = 7
Thousands: 7 - 6 = 1
Ten-thousands: 9 - 4 = 5

→ 51754

Check: 46746 + 51754 = 98500?
46746 + 50000 = 96746; +1754 = 98500 ✔

Problem 14: 39999 - 27362

9 - 2 = 7
9 - 6 = 3
9 - 3 = 6
9 - 7 = 2
3 - 2 = 1

→ 12637

Check: 27362 + 12637 = 39999?
27362 + 12000 = 39362; +637 = 39999 ✔

Problem 15: 53892 - 43750

2 - 0 = 2
9 - 5 = 4
8 - 7 = 1
3 - 3 = 0
5 - 4 = 1

→ 10142

Check: 43750 + 10142 = 53892?
43750 + 10000 = 53750; +142 = 53892 ✔
